Working Principle of Automatic Cartoning Machine

The feeding process of an automatic cartoning machine generally consists of three inlets: the instruction leaflet inlet, the vial/drug inlet, and the carton blank inlet. The entire process from carton feeding to final packaging can be divided into four stages: carton lowering, opening, filling, and closing.

The carton lowering action typically involves a suction cup picking up a carton from the carton feed inlet, lowering it to the main cartoning line, where a guide rail slot secures the carton. A push plate then opens the carton, while two forward-moving clamps rise from below to grip the sides of the carton from the front and rear, positioning it at a right angle and moving it forward to the filling area.

After filling in the filling area, the machine’s mechanism folds the tabs into the left and right guide rails, followed by the closing action. Before closing, the mechanism bends the carton’s tuck flap, and a push plate presses the lid to fold, ensuring the tuck flap is inserted into the box and the lock is engaged. The closing action is critical, and its success highly depends on the carton structure and the precision of machine adjustments.
